AS40-PLUS Comet Plus Amplifier System
User Manual
Grass Technologies amplifiers are world-renowned in the field of neurophysiology for their quality, reliability, simplicity, and serviceability At the heart of the Comet-PLUS EEG is the AS40-PLUS Amplifier System. The amplifier system is designed specifically for the EEG and PS monitoring lab and combines the latest digital design techniques with years of amplifier design and manufacturing experience The AS40-PLUS is a compact 5-channel amplifier unit. There are 40 AC channels and 4 DC channels built into the system An optional 8-channel DC input module, patient event button, and and optional pulse oximeter allow tor an additional 13 channels of data. This flexibility allows or a wide range of physiological parameters to be monitored and recorded.
The amplifier system provides tor patient safety isolation, signal conditioning (physiological signal amplification and filtering), and digitization, Communications with a host computer are accomplished using 7Op/P protocol over a 10Bas8T Ethernet network or dedicated cable. A host computer, using Win software, sets the sample rate starts and stops the data transmission, and monitors the digital data. and stores it on a hard disk.
An intuitive user interface with an LCD screen is present with the amplifier.
From the amplifier itself, a user is able to implement such features as electrode impedance checking, amplifier calibration, and phobic stimulator control. Aliso from the LCD display a user is able to obtain information such as connection status to the host computer, and oximetry/pulse rate information when an oximeter is in use.
Personality Modules: The flexible design of the amplifier allows different Personalty Modules to be used.
The PM PLUS Universal Personality The module is supplied with the amplifier in Comet EEG-PLUS systems.
The UPM-PLUS has 32 referential EEG inputs, 1 reference input, 1 patient ground, and 8 bipolar AC channels for a total of 0 40 channels. The Personality Module’s design allows tor an easy disconnect/reconnect to the amplifier system An optional $P4-PLUS, Sleep Personality Module is also available 
Photic Stimulator
Photic Flash or Photic Activation during EEG Procedures.
The Photic Stimulator is an arm-mounted photic stimulator that is designed for photic activation of the EEG and routine clinical procedures in visual evoked potentials. The Photic Stimulator generates flashes of white light by means of a light-emitting diode (LED array which switches on and off.
